       xzdec, lzmadec - Small .xz and .lzma decompressors

       xzdec [option]...  [file]...
       lzmadec [option]...  [file]...

       xzdec  is  a liblzma-based decompression-only tool for .xz (and only .xz) files.  xzdec is
       intended to work as a drop-in replacement for xz(1) in the most common situations where	a
       script has been written to use xz --decompress --stdout (and possibly a few other commonly
       used options) to decompress .xz files.  lzmadec is identical to xzdec except that  lzmadec
       supports .lzma files instead of .xz files.

       To  reduce  the	size of the executable, xzdec doesn't support multithreading or localiza-
       tion, and doesn't read options from XZ_DEFAULTS and XZ_OPT environment  variables.   xzdec
       doesn't	support  displaying  intermediate  progress information: sending SIGINFO to xzdec
       does nothing, but sending SIGUSR1 terminates the process instead  of  displaying  progress

       -d, --decompress, --uncompress
	      Ignored for xz(1) compatibility.	xzdec supports only decompression.

       -k, --keep
	      Ignored for xz(1) compatibility.	xzdec never creates or removes any files.

       -c, --stdout, --to-stdout
	      Ignored  for  xz(1)  compatibility.   xzdec  always writes the decompressed data to
	      standard output.

       -q, --quiet
	      Specifying this once does nothing  since	xzdec  never  displays	any  warnings  or
	      notices.	Specify this twice to suppress errors.

       -Q, --no-warn
	      Ignored for xz(1) compatibility.	xzdec never uses the exit status 2.

       -h, --help
	      Display a help message and exit successfully.

       -V, --version
	      Display the version number of xzdec and liblzma.

       0      All was good.

       1      An error occurred.

       xzdec doesn't have any warning messages like xz(1) has, thus the exit status 2 is not used
       by xzdec.

       Use xz(1) instead of xzdec or lzmadec for normal everyday use.  xzdec or lzmadec are meant
       only  for  situations  where it is important to have a smaller decompressor than the full-
       featured xz(1).

       xzdec and lzmadec are not really that small.  The size can be reduced further by  dropping
       features  from liblzma at compile time, but that shouldn't usually be done for executables
       distributed in typical non-embedded operating system distributions.  If you need  a  truly
       small .xz decompressor, consider using XZ Embedded.
